Salted Butter
5.0best for bakingDairy-free, add pinch of salt
Baking with margarine relies on its 80% fat, 16-20% water emulsion and 95-100°F melt point — lower than butter's 90-95°F, meaning margarine cookies spread further and flakes in pastry shorten less sharply. Swaps must match the fat-water ratio or you'll shift crumb structure at 350°F. This page ranks subs first on total fat content (for gluten shortening), second on melt-point (for pastry flakiness), third on how the swap's water content shifts batter hydration. Pure oils need recipe rebalancing; solid fats drop in closest.
Dairy-free, add pinch of salt
Salted butter at 1:1 cup matches margarine's 80% fat and similar moisture (butter is 82% fat, 16% water). Reduce recipe salt by 1/4 tsp per cup butter used, since salted butter adds ~1/4 tsp salt per stick. At 350°F the crumb browns 10% faster due to milk solids and the flavor reads richer than margarine's neutral profile.
Adds tang and moisture; use 1:1 in baking for tender crumb, not for spreading
Sour cream at 1:1 cup is not a direct structural swap — its 19% fat means far less gluten shortening, producing denser, cake-like crumb rather than tender flake. Use only in recipes where tenderness comes from acid + fat interaction (pound cakes, muffins). Cut baking soda by 1/4 tsp per cup to offset sour cream's pH 4.5 acidity.
Dairy-free swap, similar texture
Unsalted stick butter at 1:1 cup delivers 82% fat versus margarine's 80% — effectively identical structural behavior at 350°F. Higher 90-95°F melt-point means cookies spread less and pastry layers hold flakier definition. Flavor reads richer due to the 2-3% milk solids; crust browns slightly darker over 35-40 minute bakes.
Dairy-free, solid at room temp, slight coconut taste
Refined coconut oil at 3/4 cup per cup margarine plus 3 tbsp water balances the 100% fat versus 80%. Solid at 65°F, melts at 76°F — sits between shortening and margarine behavior. Flavor is neutral when refined; virgin adds coconut note. Works in vegan baking at 350°F with comparable crumb tenderness to margarine.
Use less, best for savory baking and cooking
Olive oil at 3/4 cup per cup margarine plus 3 tbsp water (100% fat versus 80%) produces a denser, more cake-like crumb because liquid fat coats gluten more aggressively than solid. Flavor carries into baked goods — use light olive oil for neutrality. Best in olive-oil cakes, focaccia, and Mediterranean-style quickbreads.
Richer flavor, no water content so reduce by 1 tbsp
Ghee at 3/4 cup per cup margarine plus 3 tbsp water — 100% fat compared to margarine's 80%. The clarified-butter nutty-caramel note deepens shortbread, cookies, and pound cake flavor at 350°F. Slightly lower browning speed than butter due to no milk solids; adjust bake time +2 minutes for even crust color.
Neutral taste, use 3/4 cup; best for moist cakes
Avocado oil at 3/4 cup per cup margarine plus 3 tbsp water balances fat content (100% vs 80%). Neutral flavor makes it a drop-in for olive oil in cakes without the Mediterranean flavor profile. At 350°F crumb reads denser than margarine's. Works especially well in almond-flour or banana-based baked goods.
Use 3/4 cup oil per cup, works in quick breads
Reduce amount, whipped is aerated
Adds dairy flavor and slight saltiness; firmer texture makes flakier pie crusts and pastries
